In the video, 48-year-old Jeff Heeszel fires these newly-created, 3D-printed, plastic slugs from his Mossberg 590 shotgun. He fires two shells and the first two slugs hit their targets from a range of about 25-30 feet. One slug blasts through a 2×12 piece of wood and the other penetrated a water jug. A third slug, shot at a closer range, knocked over a mannequin.

The bullets were sent to Heeszel by his friend, Tony Griffy, a 50-year-old design-build contractor from Chattanooga, Tennessee.

Contrary to the creator of the first printable gun, Cody Wilson, Heeszel isn’t an anarchist or political activist. He runs a funny YouTube channel that focuses on producing slow motion videos of silly putty and sausages being shot out of shotguns. He also describes himself as a redneck who loves technology.
